The supply chain plays an indispensable role in ASEH’s corporate sustainability development. The ASEH board of directors is the highest decision making body of our supply chain management, and is responsible for endorsing key strategies and execution plans.To further our sustainability goals, the Corporate Sustainability Committee was established to plan and supervise the company’s sustainability management,submit progress and status reports to the board of directors, and establish the sustainability management policies and goals of the three subsidiaries. The ASEH Board of Directors has approved the creation of a Chief Procurement Officer position and appointed Mr. Andrew Tang, a member of the board, to execute the company’s supply chain strategies, and oversee the progress and execution of major initiatives.  Each ofthe three major subsidiaries under ASEH has a Supply Chain Management Team that formulates supply chain sustainability management strategies, set medium- to long-term management goals and action plans, assess ESG issues and risks related to supply chain management, and provide necessary support, advocacy,and training as part of the team's day to day management.

Code of Business Conduct and Ethics as well as the Responsible Business Alliance (“RBA”, Formerly EICC) Code of Conduct , and we require Suppliers’ business conducts to strictly comply with this Code as well as laws and regulations of countries/area where suppliers’ operations exist with respect to labor, health and safety, environmental, business ethics and the management system. ASE also encourages Suppliers to require their suppliers, contractors, services providers and subcontractors to adopt and comply with this Code. Suppliers’ status of compliance with this Code will be one of the considerations for ASE’s evalsuation of and decision making on the purchasing. This Code consists of five sections. Sections A, B, and C outline tenets for Labor, Health and Safety, and the Environment, respectively, and Section D sets forth tenets for business ethics, and Section E outlines the elements necessary to an appropriate management system to implement this Code.

ASEH is committed to building solid supplier relationships and engaging in responsible procurement practices. While cost and quality are primary factors influencing our procurement decisions, we place an equally high emphasis on the overall sustainable value provided by the supply chain. We actively address emerging sustainability issues and risks in the supply chain, develop detailed management strategies, implement them through realistic action plans, and conduct dynamic and timely risk and opportunity assessments. In recent years, we have designed innovative programs that encourage supplier collaboration on sustainability topics. This further strengthens supplier resilience and collaboration for a win-win ecosystem.
